A canonical realization of the Weyl BMS symmetry

A canonical realization of the Weyl BMS symmetry

We construct a free field realization of an extension of the BMS algebra in 2+1 dimensional space-time. Besides the supertranslations and superrotations, the extension contains an infinite set of superdilatations. We also comment the difficulties that appear when trying to extend the algebra to that...
